SNC-M1, round two
[Last time|http://www.artificis.hu/node/154] I stopped at firmware upgrade. Got a hint from [Josephus|http://jauzsi.hu], so downloaded /dev/mtd0. It was cramfs. Later we planned [REing|http://www.multimedia.cx/eggs] the updater.cgi to get an idea about the firmware format it wants.
Thanks god this was not needed, searching after a nightly sleep made results. Now I have a firmware image.
Firmware links:

- [Direct link to v1.09 CE|http://bssc.sel.sony.com/Professional/onsite/documents/SNC-M_v109-CE.zip] (CE maybe equals to (Continental) Europe?)
I had not much time lately, but at first sight the image is like this:
- starting from 0×0 is the bootloader
- from 0×10000 follows the not compressed kernel image
- from 0xf0000 follows the cramfs root image
- the unused parts are stuffed with 0xff.
Note: this is surely not a complete description, CRCs must be there! :)
Also last time I forgot some link to the a review of the actual device. [Here it is|http://www.engadget.com/entry/5325555111254201/].
Interesting is to mention the processor. It’s made by Texas Intruments and has a CPU, DSP and other interesting parts, like USB, Secure Digital, Memory Stick, Smart Media and Compact Flash connectivity. Combined this with the Sony SNC-M3 which has a WiFi device, it is a kicking device for hackers. Bad part is it’s price.
The CPU is a TMS320DM270:
